3) is an incorrect assessment. As an example it is very easy to generate 500 random data points sampled from a normal distribution mean 0 variance 1. It is much harder to go in reverse, taking those 500 points and saying "these come from a normal distribution mean 0 variance 1".
Point is that the random number generation problem is significantly easier than the random number modelling problem.
One possibility: Record a human mouse movement, and then just reuse that same movement every time. For them to search a database of all used movements would be prohibitively expensive.
"One can imagine how X could be a problem therefore X is a problem" is a fallacy. I can imagine that unicorns exist. That doesn't mean (unfortunately) that they exist.

Setting the limits isn't tricky. The police should be held accountable to the same laws as the rest of us. There. Easy.

I assure you that the only reason some one of the 7b people on this planet hasn't shoved a gun into your back and taken everything you have is because you have a friend with a bigger gun guarding that back. Not to say that you shouldn't be discerning as to who your friends are, but there is no liberty without either bloodshed or MAD. The minute you put down your gun someone will pick it up and point it at you. C'est la humanité.
